THOMAS'M. EYNON, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO EYNON-EVANSMANUFACTURING COMPANY, A CORPORATION OF PENNSYLVANIA.

BLOWER.

ALBECIFICATION forming part of Letters Patent No. 742,618, dated October27,

' Application filed March 17, 1902- Be it known that I, THOMAS M. EYNON,a citizen of the United-States, .residing in the city and countyofPhilade1phia,State of Pennsylvania, have invented a new and usefulImprovement in Blowers, of which the following is a specification.

My invention relates to an improved construction of a blower which isadapted for gasproducers, boiler-furnaces, and other similar locations,the blower when used for boilerfiring being exceedingly effective inproduc ing a blast perfectly under control and with a minimumexpenditure of steam, the invention being especially useful in furnaceswhere inferior grades of fuel-such as screenings, gas-works breeze, andother refuse products must be burned and providing a means for with anykind of fuel.

The blast produced by my improved construction of steam-jet blower whenapplied to a boiler-furnace not only prevents the clinkduces a gas bythe decomposition of the steam that greatly increases the combustion ofthe coal or fuel used.

The present invention consists more especially in a blower having anadditional series of auxiliary air-induction ports located at a pointbeyond the larger discharge-nozzle and in proximity to the throat of thecombining or coinmingling tube, whioh discharges the commingled steamand air to the desired point, whereby an increased efficiency of fromfifteen to twenty per cent. is attained, all as will be hereinafter setforth, and particularly pointed out-in the claims.

Figure 1 represents alongitudinal sectional view of a blower embodyingmy invention. Fig. 2 represents a longitudinal sectional view of anotherembodiment of my invention. Fig. 3 represents a perspective View of theupper portion of the casing seen in Fig. 1.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawings, 1 designates a steam-pipe for conductingsteam to the nozzle 2, whereby air is drawn in, from the ports 3 and thecommin gled steam and air are discharged into the nozzle 4:, aroundwhich arelocated Serial No. 98,541. I (No model.)

the air-inlet ports 5, whereby additional air is drawn into thedischarge-nozzle 6, in proximity to which are the ports '7, thecommingled steam and air being discharged into the throat 8 of thecommingling or combining tube 9, which may lead to any desired point,all of the above parts being of the usual construction.

I have found by practical experiments that the efficiency of blowersconstructed as above described can be greatly increased by the provisionof an additional or auxiliary series of air-induction ports 10, whichare located at or in proximity to the throat 8 beyond the extremity ofthe discharge-nozzle 6, whereby an additional supply of air isintroduced into the commingling-tube 9.

I have found by practical experiments that the efficiency of blowersprovided with these additional air-induction ports 10, located at or inproximity to the throat 8, is increased by from fifteen to twenty percent. In practice I surround the nozzles 3, 4, and 6 with a suitablecasing, as 11, (seen in Fig. 1,) which latter may be provided with acover or plate 12, which can be laterally turned into the desiredposition upon the bolt as a pivot, (seen at the upper left-hand portionof Fig. 1,) so as to serve as a damper and permit the admission of agreater or less quantity of air as may be desired.

In the construction seen in Fig. 1 I have shown the casing 11 as securedto. a flange or other support 13, which is located exteriorl'y to theauxiliary air-induction ports 10, while in Fig. 2 I have shown thecasing 14 as secured to the flange or other support 15,which is solocated with respect to the auxiliary air-induction ports 10 that itcompletely incloses said ports, the amount of air passing into the ports3, 5, and 7, as well as the auxiliary induction-ports 10, beingcontrolled by a suitable damper 16, which can be located in theair-supply pipe or air-conductor 17,which latter may be extended throughthe roofof ICO blower, as may be desired or expedient, it being,however, apparent that the best results will be secured by locating saidports in substantially the angle and position shown.

I desire it to be understood that my present invention is clearlydiiferentiated from and is a great improvement over the prior deviceswith which I am familiar, wherein no auxiliary ports, as 10, areemployed for the purpose hereinabove explained and wherein no throat, asthe part 8, exists and wherein there is no commingling-tube, since bythe novel com bination of a series of nozzles a commingling-tube andthroat intermediate said 11ozzles and commingling-tube and auxiliaryairinduetion ports 10, located intermediate said nozzles and throat, Ihave produced a novel construction and am enabled to attain advantagesgreatly superior to any of the devices with which I am familiar.

It will be apparent that slight changes may be made by those skilled inthe art in the manner of assembling the parts above described, and I donot, therefore, desire'to be limited in ever i instance to the preciseconstruction I have herein shown and described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a blower,a throat,a c0mminglingtube into which said throatdischarges, means for discharging commingled steam and air into saidthroat, and a series of auxiliary air-induction ports located inproximity to said throat, intermediate of the latter and said means.

2. In a blower, a series of discharge-nozzles of varying size for steamand air, a commingling-tube for said steam and air, a threatintermediate of said nozzles and eomminglingtube into which latter saidthroat discharges, and a series of auxiliary air-induction ports locatedintermediate of said throat and the larger of said discharge-nozzles.

3. In a blower, a series of discharge-nozzles for steam and air, acommingling-tube for the steam and air, a threat intermediate of saidnozzles and eommingling-tube,a series of auxiliaryair-induction portslocated intermediate of said throat and said nozzles, and a casingsurrounding said nozzles.

4. In a blower, a series of discharge-nozzles forsteam and air, acommingling-tube for said steam and air, a threat intermediate of saidnozzles and tube, a series of auxiliary air-induction ports located inproximity to said throat and intermediate of the latter and the nearestof said nozzles, a flange or other support on said eomm-ingling-tube,and a casing supported upon said flange.

5. In a blower, a series of discharge-nozzles for steam and air,acommingling-tube for said steam and air, a throat intermediate of saidnozzles and tube, a series of auxiliary air-induction ports located inproximity to said throat intermediate of the latter and the nearest ofsaid nozzles, a flange or other support on said commingling-tube, and acasing supported upon said flange, in combination with means on saidcasing for regulating the admission of air to said nozzles.
